For ultimate cargo protection, you can’t beat a rugged, hard tri-fold bed cover, like the UnderCover® Flex from RealTruck®. The premium truck bed cover offers a robust and secure hard-shell construction, easy-to-use folding design, low-profile aesthetic, and exceptional weather resistance, protecting your truck bed in all conditions.
The UnderCover Flex Tonneau Cover features rigid yet lightweight aluminum panel construction for superior durability. These panels are impact, abrasion, and cut-resistant—they can even support up to 400 pounds when evenly distributed. UnderCover treats the Flex Tonneau Cover with a durable gloss-black coating for superior corrosion resistance and sleek styling.
Accessing your truck’s cargo area is simple and quick—simply drop the tailgate, pull either of the cover’s release cables, and fold the cover onto itself toward the bulkhead. You can secure the cover in the ⅔ open position with the integrated safety straps or fold it flush against the rear window, securing it with built-in prop rods for 100-percent bed access. When you’re finished loading or unloading, close the tonneau cover, fasten and lock the tailgate, and your cargo in the bed is safer than your cargo in the cab. Installing the UnderCover Flex is just as easy using UnderCover’s clamp-on mounting system.
The UnderCover Flex is just as resistant to inclement weather as it is to theft. The tonneau cover’s EPDM rubber hinges, perimeter seals, and dual-action tailgate seal prevent moisture from seeping into the bed. Any water that slips past the side seals gets diverted through built-in water channels and out of integrated drain tubes, keeping your cargo dry.
UnderCover is a RealTruck® brand. When you order this tonneau cover or any other UnderCover product from us, you’re dealing directly with the manufacturer. We back each UnderCover Flex Tonneau Cover with a limited 3-year warranty against manufacturing and material defects.
The UnderCover Flex Tonneau Cover features a simple clamp-on installation—no drilling is required. UnderCover includes all necessary hardware and instructions for straightforward at-home mounting.

TERMS OF THIS WARRANTY
UnderCover, Inc. warrants the structure of your cover to be structurally free from defects in material and workmanship for (3) three years from the retail date of purchase. The hinges, seals, and hardware are warranted to be free from defects in material and workmanship for (3) three years from the retail date of purchase. This warranty applies only to the original purchaser and is nontransferable. Your original sales receipt will serve as proof of purchase for this warranty. Before credit can be issued on a warranty claim, proof of defect may be required. This can be determined at the time of the claim.
EXCLUSIONS OF THIS WARRANTY
Not covered under this warranty is failure due to neglect, improper installation including any modifications to installation hardware, alterations, addition of equipment, abuse, accident, weather related damage, exposure to chemicals that are not labeled "safe for rubber" and normal wear from lack of maintenance.
CAUTION
Always read the ingredients of any product you are using to clean your cover. Make sure that you use only products that are safe for use with rubber. Many chemicals contain material that will permanently discolor or damage your cover hinges and seals. This is not considered a manufacturer defect.
OWNER RESPONSIBILITIES
Incidental or consequential damage or loss of contents due to use, neglect, lack of maintenance, misuse or abuse of the cover is the sole responsibility of the truck owner and operator. Paint damage to your truck is not covered under this warranty. When operating your truck always keep the cover in either the fully closed and latched position, or one of the two approved open positions. The first approved open position would be the first, second, and third panel stacked onto the forth panel and the buckles must be secured together. The second approved open position would be all four panels standing up vertically behind the cab. In this position both prop rods must be attached and the buckles secured. Do not operate the truck at excessive speeds with the cover in either open position.
REPAIR AND REPLACEMENT
In the event that your cover is found to be defective under the terms of this warranty, it is at the discretion of UnderCover, Inc. to repair or replace the defective part. All repairs must be made under the direction of UnderCover Inc. UnderCover Inc. is not responsible for any transportation costs associated with the warranted claim.
MAINTENANCE & CARE
The panels of your cover require only periodic cleaning with mild car wash soap. Avoid use of all abrasive type cleaners as they may dull the finish. Some chemicals and fluids such as insect repellents, oils, solvents, and lubricants could potentially damage the rubber hinges and seals and void the warranty.
